South Korea will make its third attempt to launch the Naro space rocket on Thursday. South Korean and Russian scientists smoothly completed on Wednesday the final rehearsal for the launch of the Naro, according to Korea\'s (KBS WORLD) website. The scientists focused on inspecting a connection between the first-stage rocket of the Naro and the launch pad where helium was found to have been leaking during a previous launch attempt last month. The scientists confirmed with the inspection that there were no malfunctions. Weather conditions are not expected to affect the launch.
